The value of \(\beta \)  decreases with altitude above the solar surface. In the photosphere (\(\beta >1\) ), plasma pressure dominates over the magnetic force. Below the solar surface it increases with depth and reached upto 10\(^5\)  near the convection zone. In the solar corona \(\beta <<1\) , hence the energetics and dynamics are governed by the magnetic field ([1]}; [2]}).
